Recursion Error in PPR

[Former Member]

Hi Experts,

We are usging APO 3.0A and encounterred recursion error when we run PPR for automatic planning.

Actually, our production have recursion process as follows.

FInished Product-A (1,000Kg) (filled in Drum)

--- Semi-finished Products-B (1,000Kg) Semi-finished Product-B (1,000Kg)

|--- Finished Products-A (50Kg) (as components for semi-finished products)

Is there any way to make plan automatically in APO PPDS like a "Recurs. Allowed" flag in master recipe in R/3?

Thank you so much.

Hi,

1) In R/3 you need to define and maintain your components and sub-components

with finished products very accurately to avoid recursion error

2) Normally if a finished product has a list of items which has multiple components,

and if one of the component is planned repetatively, this leads to this error

3) Run low level code before you start automatic planning and check

Hi Senthil,

Thank you so much for your reply.

Actually we tried to run the PPR for the Low Level Code again, but the problem still has been occured... But can I understand that normally this kind of direct recursive planning (A is component of B. And B is component of A) is possible in APO if we completed to run heuristics for low level code correctly?

Hi,

Recursion error is common phenomenon in PPDS heuristics.

Low level code sometime clear this error depending upon

your bom structure. If it is too complex, then you may have to

apply sap note to correct the program error.

check sap note 588857 or similar note to permanently fix

this issue
