Set maximum size for attachments in MTE

Hi experts,

We are busy implementing the SAP Fiori app My Travel and Expenses. We want to set a maximum size for attachments to upload on detail level. We created an archive link to the SDOKCONT1 table. In order to be sure that users will not upload huge documents we want to set a maximum.

A related question: we found that after uploading 10 attachments the "+" button is disabled. Is there a possibility to change the maximum number of attachments to be uploaded per receipt?

Thanks for your advice.

Regards,

Marius Hardonk
