How to Protect SD ALV Reports from Unwanted Changes

You can prevent changes to SAP List Viewer (ALV) report layouts in sales and distribution (SD) by activating the save ALV variants functionality. The save layouts pop-up screen is not a bug, as some users think, but a user parameter that the user administrator usually sets.
Key Concept

To restrict users from changing sales and distribution (SD) report layouts in the SAP List Viewer (ALV), you can define authorizations in the user role. The user parameter that controls the access for changing of SD report layouts is SD_VARIANT_MAINTAIN (authorization for variant maintenance).

When a user working with sales and distribution (SD) reports wants to save an SAP List Viewer (ALV) variant, it is common that the option to save the layout is grayed out and disabled. This occurs even if the user has the SAP_ALL authorization. A user parameter for maintaining authorizations allows you to save those variants and make them available for users. I tested this process in SAP R/3 4.6C, but it is valid for later releases such as SAP ERP Central Component (SAP ECC) 6.0.

Users who want to manage the Save Variants function in SD reporting should ask the authorizations administrator to define the parameter in the user role. In the standard system, this parameter is not activated by default. When the administer changes the parameter, the user does not need to log on again to activate the authorizations. Table 1 shows all possible values for parameter SD_VARIANT_MAINTAIN. Standard variants can be used by all users in the system, but user-specific variants can be used only by the user, who has created the variant.
