In Microsoft Project, when you run a Microsoft Visual Basic for Applications macro that assigns a material resource, you may receive the following error message:
Run-time error '1101':
The argument value is not valid.
This behavior occurs when you run a Visual Basic for Applications macro that uses the Add method to assign a material resource and includes a variable material consumption rate in the Units value, for example, 2/d or 2/wk.
For example, the following macro generates the error described above:
This behavior occurs because the Units argument of the Add method accepts only an integer or decimal value. Other alphanumeric characters are invalid.
Note that if the macro is assigning a work resource rather than a material resource, a percent (%) sign included in the Units value generates the same error.

To work around this problem, assign the material resource first; then modify the units for the assignment to add the variable material consumption rate.
For example, the following macro assigns a material resource and then changes its units to 2 per day:
