1st, finished product warehousing, but the material all has not sent, after the computation material cost can lower.The warehouse 2, the labor only deletes, only the positive number material leaves the storehouse only to form a complete set with the labor the storehouse, separates the month rejected material also is necessary draws back with the labor list, after if draws back, only deletes this labor, then in the deletion same month rejected material cannot with the labor list, take this labor single special-purpose material, but is in uses in common inside the material to manifest, with for the material expense booth which uses in common to in the same month each labor list.But in system database, can demonstrate this labor list is producing the material. The production department 3, the labor only ahead of time closes, after the closure only then goes into storage, in computation October time, the labor list 0709117, is in the same month finished product warehousing, but the system demonstration for this labor list in 9 closure, does not have the means in the cost administration module to calculate this labor list.And the production department 4, the cross month revision labor list, under the last month labor list, had the collar material to produce last month, in the next month of revision labor list, after the system revision labor list regard was a new labor list, could not be connected as for the last month collar material. 5th, the identical labor list, has the blue character in the same month to leave the storehouse also to have the red character to leave the storehouse, takes the special-purpose material and the labor when the cost administration module with the material, the blue character takes in the special-purpose material row, the red character takes in uses in common in the material, ERP system question 6, when computation cost, the end product works as is not approximately 0, the man-hour is not 0, after but calculates, when the end product man-power and the factory expense are firmly the 0, ERP system question 7, the false rejected material, because the material unit price is 5 decimal points, the final outcome causes, after the labor list false rejected material, leads the material condition is 0,But amount or positive number several minutes, either negative number several minutes.When cost finding inspection, the bulletin is wrong.The decimal point question 8, other enter with other, this operation causes the stock raw material itemized account the cost and the general ledger raw material level subject cost is not coordinated, thus does not have the means to examine the goods in stock itemized account the income sends out as well as the balance amount.Adjusts question which the allocation list causes. After 9th, calculates the cost, the examination result, the man-power and the factory expense are 0, reason: After establishes the BOM table, also deletes causes, this conclusion is a reason which the ERP guest clothing finds out, is connected the foundation establishment aspect, needs the detailed understanding to need the IT explanation.
