Sap Integrated plan - Error CL_RSPLS_DELTA_BUFFER_B e nel Form READ-07

Hi Expert,

i have created a planning function with integrated planning.

I try to use this function and i have two different response:

1. I'm going to insert new record and before to launch my planning function I save the data with the standard function. In this case my planning function run.
2. I'm going to insert new record and without save data, I launch my planning function. In this case i have this error: CL_RSPLS_DELTA_BUFFER_B e nel Form READ-07

The patch level is SAPKB70108.
