Yes, I know the invoice sequence. However it does not use the
GenericDelegator.getNextSeqId() method but uses it own service: getNextInvoiceId in component://accounting/script/org/ofbiz/accounting/invoice/InvoiceServices.xml It's a simple ( xml ) service. My suggestion was regarding the SequenceBank - to add additional feature to that class.

As a custom in your system that is ok
as for the Trunk that may not be feasible. however a custom to deal with more that just invoice might be accepted.

This is an interesting idea, although it makes me wonder... why not just use the same technique that the getNextInvoiceId service uses? -David On Jun 22, 2009, at 9:01 AM, Deyan Tsvetanov wrote: > I recall my comment about the sequences thread safety - in case we > start > 2 ofbiz instances against the same database :) > > But the 1st issue remains - configuring the sequence bank size for > specific entities. > > I suggest adding a new column in SequenceValueItem - bank_size. > If it is set to 0 than SequenceUtil will not create a SequenceBank for > that entity but will read the current seq_id from the database > instead. > This is needed to ensure there will be no gaps in the sequence IDs for > entities that do require no gaps because of legal requirements in some > countries :) > > -- deyan > > > On Mon, 2009-06-22 at 17:30 +0300, Deyan Tsvetanov wrote: >> Hi again, >> >> finally I used GenericDelegator.getNextSeqIdLong() when creating >> entities. >> >> It does increment the sequence by 1. >> >> However today I noticed, that in the database - sequence_value_item >> table - the seq_id value gets incremented by 10. >> >> The reason is that the org.ofbiz.entity.util.SequenceUtil class >> creates >> a SequenceBank with the default value ot 10 IDs. >> >> This is a MAJOR problem.

well,
it's easier for me to just copy+paste the getNextInvoiceSeq service, but i wanted to use a general sollution - less code to worry about :) and it thist feature would be definitelly used, lot of countries have the requirement for no gaps in ids. also there is an requirement to re-start the counter on certain periods. for example id should be year+sequence id. in getNextInvoiceId that's implemented. i thought of suggesting this feature as well, but theb i thought - it's pretty easy to make a service and schedule it yearly... so that goes away. but the SequenceBankSize prop i do think will be useful, so if you guyz agree than i'll go ahead and implement it. i'll do it anyway - i need this feature for a project :) -- deyan ------- Original message ------- > From: David E Jones <[hidden email]> > To: [hidden email] > Cc: [hidden email] > Sent: 22.6.'09, 21:22 > > an interesting idea, although it makes me wonder... why not just use the > same technique that the getNextInvoiceId service uses? > > -David > > > On Jun 22, 2009, at 9:01 AM, Deyan Tsvetanov wrote: > >> I recall my comment about the sequences thread safety - in case we >> start >> 2 ofbiz instances against the same database :) >> >> But the 1st issue remains - configuring the sequence bank size for >> specific entities. >> >> I suggest adding a new column in SequenceValueItem - bank_size. >> If it is set to 0 than SequenceUtil will not create a SequenceBank for >> that entity but will read the current seq_id from the database instead. >> This is needed to ensure there will be no gaps in the sequence IDs for >> entities that do require no gaps because of legal requirements in some >> countries :) >> >> -- deyan >> >> On Mon, 2009-06-22 at 17:30 +0300, Deyan Tsvetanov wrote: >>> Hi again, >>> >>> finally I used GenericDelegator.getNextSeqIdLong() when creating >>> entities. >>> >>> It does increment the sequence by 1. >>> >>> However today I noticed, that in the database - sequence_value_item >>> table - the seq_id value gets incremented by 10. >>> >>> The reason is that the org.ofbiz.entity.util.SequenceUtil class >>> creates >>> a SequenceBank with the default value ot 10 IDs. >>> >>> This is a MAJOR problem.

Deyan, I still can't figure out what you are trying to do. You mentioned that countries have a requirement for no gaps in ID values, but which ID values are you referring to? I know such requirements exist for things like invoice IDs and even certain others like returns and orders, and that is why code exists to take care of those cases. Which other cases are you trying to address? -David On Jun 22, 2009, at 12:39 PM, Deyan Tsvetanov wrote: > well, > it's easier for me to just copy+paste the getNextInvoiceSeq service, > but i wanted to use a general sollution - less code to worry > about :) and it thist feature would be definitelly used, lot of > countries have the requirement for no gaps in ids. > > also there is an requirement to re-start the counter on certain > periods. for example id should be year+sequence id. > > in getNextInvoiceId that's implemented. i thought of suggesting this > feature as well, but theb i thought - it's pretty easy to make a > service and schedule it yearly... so that goes away. but the > SequenceBankSize prop i do think will be useful, so if you guyz > agree than i'll go ahead and implement it. i'll do it anyway - i > need this feature for a project :) > > -- deyan > ------- Original message ------- >> From: David E Jones <[hidden email]> >> To: [hidden email] >> Cc: [hidden email] >> Sent: 22.6.'09, 21:22 >> >> an interesting idea, although it makes me wonder... why not just >> use the same technique that the getNextInvoiceId service uses? >> >> -David >> >> >> On Jun 22, 2009, at 9:01 AM, Deyan Tsvetanov wrote: >> >>> I recall my comment about the sequences thread safety - in case we >>> start >>> 2 ofbiz instances against the same database :) >>> >>> But the 1st issue remains - configuring the sequence bank size for >>> specific entities. >>> >>> I suggest adding a new column in SequenceValueItem - bank_size. >>> If it is set to 0 than SequenceUtil will not create a SequenceBank >>> for >>> that entity but will read the current seq_id from the database >>> instead. >>> This is needed to ensure there will be no gaps in the sequence IDs >>> for >>> entities that do require no gaps because of legal requirements in >>> some >>> countries :) >>> >>> -- deyan >>> >>> On Mon, 2009-06-22 at 17:30 +0300, Deyan Tsvetanov wrote: >>>> Hi again, >>>> >>>> finally I used GenericDelegator.getNextSeqIdLong() when creating >>>> entities. >>>> >>>> It does increment the sequence by 1. >>>> >>>> However today I noticed, that in the database - sequence_value_item >>>> table - the seq_id value gets incremented by 10. >>>> >>>> The reason is that the org.ofbiz.entity.util.SequenceUtil class >>>> creates >>>> a SequenceBank with the default value ot 10 IDs. >>>> >>>> This is a MAJOR problem.

Hi David,
i am currently not referring only business organizations but government organizations as well. Ridiculous but still organizations ( and customers :) I'll give you an example: documents management - each incoming document MUST get an incoming number which MUST be sequential with no gaps ( so they can track the order the docs were received and make sure nobody fakes the date, or at least this was the way it was done 100 years ago when all the registers were on paper :) then you get outgoing documents - same thing. Then you get support ticket numbers: the organization must issue an incoming ticket number to the ticket creator - either on paper, signed and stamped, or via e-mail - digitally signed. The number has to has no gaps - in case it gets argued or goes to court ... or whatever. I could quote hundreds of cases which no gaps are required by our lovely government agencies and organizations. The country is called Bulgaria :) So my current project is related to bailiffs. These guys in general are a private business, but most of their activities are defined by the law. So the law tells them how they should number their cases - I can't argue - i'm just a programmer :) Neither could they - they'll loose their license if they don't comply. It's the same story with invoicing, it's the same story even with bus or cinema tickets printing ! :) Did I manage to answer your question ?

Hi again,
false alarm - no development will be necessary. I found an undocumented attribute for the entity definition which does exactly the same job: sequence-bank-size Here's an example ( how it can be done for applications/party/entitydef/entitymodel.xml ) <entity entity-name="Party" package-name="org.ofbiz.party.party" title="Party Entity" sequence-bank-size="1"> Perhaps I should focus more on documenting :)) Thanks for your support, Deyan On Thu, 2009-06-25 at 15:14 +0200, Jacques Le Roux wrote: > Yes please do > > Jacques > > From: "Deyan Tsvetanov" <[hidden email]> > > Hi guys, > > > > so - any comments on the suggested improvement ? > > > > If no than probably I could open a jira enhancement issue and attach a > > patch ? > > > > -- deyan > > > > On Mon, 2009-06-22 at 22:46 +0300, Deyan Tsvetanov wrote: > >> Hi David, > >> > >> i am currently not referring only business organizations but government > >> organizations as well.
