BAPI_PO_CHANGE - PO_SCHEDULE

Hi!

Maybe sb. could help me with following problem: I'd like to call BAPI_PO_CHANGE from a Web Dynpro to change delivery times and quantities.

In the tables PO_SCHEDULE and PO_SCHEDULEX I set the following attributes:

<i>Delivery_Date</i>

<i>Stat_Date</i>

<i>Del_Datcat_Ext</i>

<i>Quantity</i>

<i>Po_Item</i>

as well as the regarded purchaseorder-number as import-parameter.

But unfortunatly, the changes I submitted were not taken over. Could you perhaps tell me what I did wrong or forget?

Thanks a lot in advance!

BR

Thomas
