Some doubts in copy control from billing doc to invoice list

[Former Member]

Dear all,

The value of allocation number in FI doc can be customized as: A (PO number), B (Sales order num.), etc.

But how can I make it to be assigned an alternative value (for example, we have do an add-on "invoice" then we hope our invoice no. be assigned here)? Is there an exit to do so? or how this happen (especially when SO's billed, then the FI doc has been generated already.) or how a creation of invoice list will changed the value of allocation number in former FI doc created by billing before?

Thanks to all,

James

Could you give details of actual business flow?

A solution is possible if you give real business scenario.

Hi, thanks for you reply.

The business scenario as following:

The users create SO. Then post it (VF01) (billing doc and accounting doc. SO and billing is one-one relationship). But at this time, users doesn't generated the customized invoice to customer (also the customer may like to be invoiced with different SO). In order to do this, the user should do invoice list (VF21) to include former billing doc. At this moment, we hope we can update the allocation value in FI doc generated by billing before.

SO->Billing (FI doc generated) ->invoice list (Hope can update some fields in the FI doc).
