Create mass specifications and update value assignments

Hello

I have a requirement to have multiple specifications created in my SAP EHS system and update specific value assignments for them.

If I have raw data provided to me in form of an excel spreadsheet, how can I create and update mass specifications. Please note that my client does not have a license for data editor/OCC.

The spcific tasks are:

- create multiple specifications

- assign inheritance relationships for each

- update specific properties (mainly physical and chemical properties) for each

- update composition values for each.

Appreciate any inputs.

Thanks.
