What caused the error Maximum Commitment is more than that of parent agreement?

This error is caused by the parent agreement's Maximum Limit, which is less than the subagreement's Maximum Limit.

The maximum commitment value for a single subagreement cannot exceed the maximum commitment value for its master agreement, but if a master agreement has multiple subagreements, the sum of the maximum commitment values for its subagreements can exceed the master agreement’s maximum commitment value. This is aligned with the documentation Overall Contract Limits.
Product team recognizes the value of enforcing cumulative limits, and this requirement has been noted for consideration as part of the Next Generation version of the Contracts solution currently in development.
