Any other way to track grants in SAP vs 1503 besides Grant Management Module

[wing73]

We have a requirement from our financial business side of the house for tracking Grants. Here are the top five requirements:

We need a way to track grants at the expense detail level

Ability to use multiple funds on a grant

A way to certify we aren’t duplicating expenses or match on varied grants

Know when an expense is paid vs. receipted on a project that utilizes a grant

We need to ability to tag an asset with the grant (as there are parameters on the disposal of grant assets specific to each grant)

We are on SAP version 1503 and would like to know if there is another way besides implementing the Grant Management module to track grants at the expense detail level.
