Executing Planning function on a Different AggregationLevel on Save on Promotion

Hi Experts,

We've a planning layout on an Aggregation Level 1, which is directly based on a Planning DSO 1. I wanted to execute a Planning function which is based on Aggregation Level 2, which is based on a MultiProvider having two Planning DSO's 1 and 2. This Planning function will copy data from DSO1 to DSO2. This shall be executed on Save.

Now when I save the promotion, it goes to the dump of "Unassigned Field Symbol".

In this case, I can't even implement the BADI: RSCRM_IMP_QUERY for InfoProvider restriction to which the data needs to be saved because the query is based on Aggregation Level 1 which is directly based on DSO1.

It would be great to share your expert thoughts here.

Thanks & regards,

Jomy
