PS Substitutions

We have configured Partner funcitons to used at PD and WBS element level. We want to enter the 'customer number' as partner at the PD level and then want to copy it automatically in all the WBS elements under the project.

Is it possible to do such a thing? We are unable to use substitutions coz Partner fields do not occur in the substitution fields.

This is reasonably easy to achieve with substitution exit, where you can retrieve data from any logically linked objects and use these as substitution source data. This is described in note 440186, chapter 4.

However, with this technique you can only maintain the fields of PRPS, e.g. user fields USR*.

If your intention is to substitute corresponding Partner role in each level of WBS, I think that will not be possible with this technique directly.

You should additionally check if there is a user exit at partner maintenance to complete the scenario.

Normally you can use user exit RGGBS00 to insert a user specific into subsititution.

But in your case, it's a little complex, because the partner is in another table (not in PRPS). however you can try to insert your own field into table GB01 and regenerate with program RGUGBR00 (note 42615).
