SAP Note 27567 - Planned allocation: Reversing several periods

Symptom:

1) When you reverse a planned assessment or planned distribution, only one period is reversed although several periods should be reversed at the same time.
2) When you reverse a planned assessment or planned distribution, only the first period block (for example, 16 periods) is reversed although more periods should be reversed.
Caution: These errors can only occur in POOL tables.

Cause and prerequisites

re: 1) No plan line item table is implemented although plan line items are written. The plan line items are then correctly written to the actual line item table, but index table GLIDXB is not (the period is not contained in GLIDXB).
re: 2) A plan line item table is implemented, but only the first period block can be written because of a design error in table GLIDXB.

Solution
re: 1) Either define and implement a plan line item table or perform the allocation individually for each period and then reverse it.
re: 2) Always perform the allocation for an entire period (for example,
1 - 16) and then reverse it.
