1783428 - User is Able to Edit a Material Eventhough There is no Write Access


For a particular user, you have provide no Write access to Edit a Material in Product Data work center. But still the user able to Edit, Change and Save the Material.

Reproducing the Issue

Step 1: Blocking the Write access for a particular user in Application and User Management work center.

Step 2: If the user try to change a Material in Product Data work center, system still allows to change and save.


Even though, you block Write access for Material in Product Data work center. If the user is having Write Access to Material in any other work center, then the user can still be able to Edit the Material in Product Data work center.


If you want to restrict a user for changing the Material, then it is mandatory to restrict his/her Write Access to all Material views in different work centers.

For example, you can access the Materials through any of the below work centers. So, if you want to restrict an employee for changing the material, then you should give No Write Access to all the Material views that was assigned to him/her.

View: By Materials - work center: Product Portfolio

View: By Materials - work center: Product and Service Portfolio

View: Materials - work center: Product Data

View: Materials - work center: Inventory Valuation

View: Materials - work center: Audit

View: Products - work center: Supply Planning

View: Materials - work center: Product Development

Special Case:

After restricting write access to all the above workcenter/views, if the user is still able to edit a Material, then the cause could be that user has also work center views PDI_ADMINISTRATION and PDI_DEVELOPMENT in work center PDI_PARTNER_DEVELOPMENT assigned.

This implicitly grants unrestricted Read and Write Access, because this is necessary for development users in PDI. According to the documentation of the ByD Studio, those Work center views shall not be assigned to regular business users because of this fact.

Please remove the assignment of those work center views, if the restrictions on other views shall be enforced.
