INVOIC02: Assignment interference

Former Member — Fri, 01 Mar 2013 11:50:40 GMT

Hi all,

I have noticed an odd issue when posting a large invoice and immediately afterwards another small invoice through an IDoc interface. This is the scenario: two IDocs arrive, the first one is pretty big (400+ items). The line items use the assignment of the vendor in the invoice. For example, vendor is 10000, all items of this invoice have ZUONR = 10000. This is forced in user exit EXIT_SAPLIEDI_003 with ALLOC_NUMBER = VENDOR. In user exit ZXF06U06 I change the assignment of the vendor item to another value.

This seems to work fine when the IDocs are not too big, the items always have the corresponding vendor in their assignment. However, when a big IDoc arrives the numbers of the items in the document use the vendor number of the next IDoc (in the same number range). And the second IDoc uses the vendor number of the big IDoc for its item assignment values. When I force the assignments on item level in ZXF06U06, the first IDoc is good (all items have the correct assignment), however, the second IDoc still has the other value:

When I treat both IDocs seperately, the assignment value is correct. This is a very strange issue, might have something to do with DB buffering maybe?

Does anybody have any ideas? Thanks!

Just a small addition: I have also set a breakpoint in the user exit: when the second IDoc is treated, all values in the document_data tables are correct: there is no more reference to this 11858 number.

Also: when the large IDoc is preceded by another one, the items in the large IDoc take the vendor number of the one preceding it. All IDocs after this one, are then shifted: IDoc x+1's items have the vendor number of IDoc x as assignment value and so on.

Another update: When calling the 'POSTING_INTERFACE_DOCUMENT' in LIEDIF2Y:

In SAP note 127178, I read the following:

User exit 003

enables you to change the field BSEG-ZUONR (allocation number). As with 001 and 002 the exception NOT_FOUND can be triggered and a message generated as well. (Up to and including Release 4.6C, take note 330390 into account.)
The call is carried out after exit 002.
The following data is available in the exit:
- the company code of this item
- the vendor account
- batch input fields and field contents of the current line item
Name of function module: EXIT_SAPLIEDI_003
The allocation number is not filled as a default.

This is exactly what I'm doing. Has nobody ran into this issue before?
