Costing is not allowed for material/PPS status - Message no. CK 399

Hi Experts,

I am getting the following error when doing a costing run via CK11N:

***

Costing is not allowed for material/PPS status

Message no. CK 399

Diagnosis

Material XXXXXX in plant XXXX has material status Y1. The setting for this status is such that costing cannot be carried out.

Procedure

Check the material status in the costing view and MRP 1 view in the master data record of material XXXXXX in plant XXXX (Field MAT/PPS status)

***

I have already checked the status of the material in both costing and MRP 1 view via MM03. Plant-Specific Material Status is Y2 (Material productive). I am not sure if the statuses are standard but I hope anyone can advice on the solution if you have encountered this one already.

Thanks,

Josef
