unable to edit quantity in TAPA line

[Former Member]

Hi all,

we use material determination, which displays the material determined as a sub item, in this context, i have a TAPA line ( line relevant for determination) & a TAN line which TAPA brings in, which is relevant for further processing.

lets say i have a sales order created for 100 PC, where A is the TAPA line & B ( determined material) for TAN line, since i only have 70 PC, i have confirmation against this.

now i had created delivery for 20 PC for B against this sales order & wish to change the order quantity to 20, but am not able to change the order quantity at TAPA level (even on TAN line) as the quantity field is greyed out.

need to understand if this is a standard functionality ( if so why was it designed this way).

Please let me know if any had a similar issue.

Regards

Hello Ilango,

Yes, this is standard for RBA(Rule Based Availability).

Refer following SAP Note & Help link for explanation:

- Changing Sales Order Items Relevant for Rules-Based ATP Check

- Note 1398021 - RBA subitems and manual changes

Thanks, JP
