You use the Program Log grid to create and edit the Program Log transactions. MPM supplies powerful spreadsheet-like controls to make it easy. Most operations can be performed in several different ways, using either the keyboard, the mouse, or both.
To add a new Program Log transaction, press the Insert key or click Edit » Insert Log. MPM inserts a new row after the current transaction and displays <Required> in the Program Log field.
You must fill in the Log Date field when creating new Program Log transactions. See Program Log Field Descriptions.
To enter a Negotiated Cost transaction, enter the Negotiated Contract Change.
To enter an Authorized Unpriced Work transaction, enter the Authorized Unpriced Work amount.
To enter a Management Reserve (MR) transaction, enter the Management Reserve amount, and optionally, a description of the MR transaction. MR identifies contract budget set aside for contingencies. MR is always maintained at the total cost level.
To enter an Undistributed Budget (UB) transaction, enter the Undistributed Budget amount, and optionally, a description of the UB transaction. UB identifies budget not yet distributed to control accounts, usually as a result of contract changes, and is normally a temporary repository for unallocated budget. UB is always maintained at the total cost level.
To maintain the Total Allocated Budget (TAB) with a greater level of detail, you can also enter transactions which contain Prime, Overhead, Total Burdened, G&A, COM, Total Cost, and Total Dollars from the Element of Cost (Baseline — Recap) report.
When entering numeric values for contract changes, enter positive values preceded by a plus sign (+) or without a precedent; enter negative values preceded by a minus sign (-).
