  • Is it possible to leave the [value to be searched for] blank (or an asterisk) so that all of the IDocs selected will be changed?  For instance, if I’m changing the cost center on an FI document upload of 5000 documents where there are hundreds of current cost centers but I’m hard coding all of them to a new value… can that be done without specifically entering in every single existing cost center?

    • Hi Nathan,

      You mean to say * in idoc field? Means check all idoc to replace the value?

      I haven’t tried this scenario. If i get such scenario then will update you.



    • Hi Nathan,


      I checked. Note below points.

      1. * Not allowed
      2. range of idoc allowed.
      3. Multiple idocs allowed.
      4. Idoc number field left blank, still it process.

      Any more questions are welcomed.
