SAP Cloud for Customer

Reproducing the Issue

  1. Go to the Products work center.
  2. Access the Product Administration work center view.
  3. Click New.
  4. Enter the Material ID YYY&YY (where YYY&YY stands for a material ID of your choice which contains special characters).
  5. Fill the mandatory fields.
  6. Click Save.
  7. System throws the mentioned error.


The system is designed to allow only alphanumeric characters in the Product ID, along with a few special characters.


To enable the use of special characters in the product ID, scope the required question as below:

  1. Go to the Business Configuration work center.
  2. Access the Implementation Projects work center view.
  3. Click Edit Project Scope button.
  4. Navigate to the Questions section.
  5. Expand General Business Data.
  6. Next, expand Products.
  7. Select Materials.
  8. In the right-hand side, check the box for question "Do you want to create the Material ID with special characters?"
  9. Review and complete the scoping by selecting Finish

To create the Products, you may use alphanumeric characters ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789 along with special characters such as ., +, =, space, #, @, %, ( or ).


  • Special Characters such as &, {, }, <, >, * , “ and ; are not supported.
  • To create an ID with _, -, /, :, and \, scoping the question mentioned above is not mandatory.
  • When you create a product ID using consecutive spaces (for example, XXX  _YYY), the ID is displayed in the user interface as XXX _YYY with only one space. However, if you perform a search for XXX _YYY (with a single space), you will not get any results. You will have to perform a search with the same ID that you had created (that is, with consecutive space).

You may check the activity Number Ranges for Materials in the Business Configuration to understand how your system is designed to accept the characters.

  1. Go to the Business Configuration work center.
  2. Access the Overview work center view.
  3. Search and open the activity Number Ranges for Materials.
