What causes this issue?

Application component &V2& is assigned to InfoObject &V1&. This means
that the InfoObject becomes a <DS:DE.RSDISOURCEFL>master data InfoSource
</> with direct update. However, this is not possible for this
InfoObject for one of the following reasons:
the characteristic is 0SOURSYSTEM (source system ID).
The characteristic has neither master data, texts, nor hierarchies,
meaning that it does not makes sense to load data for this
characteristic.
The InfoObject is not a characteristic, but a unit, or a key figure.

System Response

The application component is deleted. This means the characteristic is
no longer an InfoSource with direct update and it no longer appears in
the Data Warehousing Workbench InfoSource tree.

How to fix this error?

If you want the characteristic to be an InfoSource with direct update,
change it so that it does have master data, texts, or hierarchies.
