Sequential number in PPDS operation

[Annemarie_de_jo]

Experts,

I would like to use the field SEQNR in PPDS operations. There is a similar field in the ECC operation (AFVGD_SEQNRV) but it is not related. At least its not included in APO operation, although we fill the field in ECC.

Is it possible to use a standard user exit on the CIF for production orders to send this field in to the PPDS order operation, do we need to use APO FM /SAPAPO/DMOPR_OPR_UPDATE.

Any of you experienced with this issue?

Thanks,

Annemaire
