If you are planning to make some modifications in your pricing calculation schema (transaction M/08), you should make sure that these changes do not lead to inconsistencies in purchasing documents that have already been created before the customizing is changed.

It is important that during this modification, the step and counter from already existing conditions are not changed, otherweise you might get error messages during goods receipt, invoicing and reversing already existing documents.

To achieve this you can:

  • Create a new calculation schema. Here you will play on the safe side. If you have to make many changes, this might be the most reasonable choice.
  • Change or add conditions to the actual calculation schema. In this case you have to make sure that you do not change the step and counter from already existing conditions.

Taking one of the above options, you should not get into trouble.

    Hi Arminda

    You have highlighted an important point which we usually forget when we make changes in pricing procedure. We come to know when user comes with some calculation problem. I don’t know if it will give error in MM pricing but in SD if we change step number for any % alculation then it will only change the value. No error comes in SD pricing from sale order to delivery or billing. But this a point which we should consider and keep in mind while doing changes in Pricing Schemas.

    Thank$

    Hi Arminda,

    Thank you for the post. I want to know more details on the option:

    “Create a new calculation schema. Here you will play on the safe side. If you have to make many changes, this might be the most reasonable choice”

         => If we take this option and assign new calculation schema to Purchase organisation,

    1. How does the existing master data objects (like Info. Records, Contracts) behave once TR is in system? do they get changed to new calcuation schema automatically?
    2. If yes, then I wont see problem with creation of new POs. if not, what activities needed?

    Thank you for your input.
