When you maintain a vendor evaluation, the system generates error message ML061 'System settings for purchasing organization xxxx incomplete'.
Check the Customizing settings for the vendor evaluation:
Ensure that at least one subcriterion is defined for every main criterion defined (Transaction OMGI). For this, also the description texts for all criteria must be maintained in the required languages. (Table T147D must contain all description texts in your language. If necessary, you must change the logon language.)
In addition, you must have ensured when maintaining the data depending on purchasing organization (Transaction OMGL) that at least one subcriterion is assigned to every main criterion assigned.
In the definition of the weighting, every main criterion assigned to the purchasing organization must be weighted.
