Substitution rule does not trigger on document reversals (FB08)

[ken_wong5]

Does anyone know why substitution rules are not triggered on document reversals (FB08).

For example, the following substitution rule is created:

1] Substitution rule prerequisite: GL=100000 AND debit entry

2] Substitution rule: Transaction type = 01

In this case, the transaction type field is properly substituted with 01 on the document posting

However, if the document is subsequently reversed (via FB08), the transaction type remains as 01 even though the following substitution rule is created:

1] Substitution rule prerequisite: GL=100000 AND credit entry

2] Substitution rule: Transaction type = 02

Note: adding tcode=FB08 in the prerequisite also doesn't work.

Has anyone successfully triggered a substitution rule on a document reversal?

Thanks Christian, I also found this note. However, the note doesn't answer the problem. Does anyone have a work around?

Hi,

well, from my point of view it answers your question.

It is not possible to substitute fields for call-up point 1-3 for document reversals, as this can cause differences between the original and the reversal document.

I've not seen a workaround and I can't imagine why it is necessary.

Best regards, Christian

Hi ,

As per the explanation provided by mr. ortner it is logical that in reversal you have to reverse the original document and why is it necessary to go for a substitution ?

well if the requirement is that genuine the you may check the feasibility with following BADi :

BADI_ACC_DOCUMENT - Method Change.

Hi,

A different transaction type is required on accrual documents reversals because the business requires additional granularity beyond the GL account (and code block assignments).

Hi,

check SAPNET note 42615 point 4:

4. A substitution for reversal postings (FB08, F.80) was defined. No substitution for callup point 1 - 3 takes place in FI for reversals, because the reversal document must resemble the document to be posted (except the exchanged debits and credits).
