When there is need to purchase material, one must check in the registered matrix for the product which suppliers and respective contracts are responsible for the item's supply and their percentages. From this data, one must check the balance of the contract items to determine whether the supplier is to take part in supplying the item. For each contract in which the item has enough balance to meet the required amount (or part of it), according to the matrix percentage, a delivery authorization must be generated for the supplier, as per the example below:
Contract | Supplier | Participation % | Balance of the contract item |
1 | A | 30 | 10.00 |
2 | B | 50 | 10.00 |
3 | C | 20 | 10.00 |
Purchase need of 10.00 units of material. In this case delivery authorizations must be generated as below:
Supplier | Contract | Amount |
A | 1 | 3.00 |
B | 2 | 5.00 |
C | 3 | 2.00 |
If there is a contract whose balance of the contract item meets the required amount only partially or does not meet it, according to the matrix percentage, and if the MV_MFREDIS parameter is enabled, the amount must be redistributed among the other contracts of the matrix (as long as there is enough balance to meet the amount), as per the example below:
Contract | Supplier | Participation % | Balance of the contract item |
1 | A | 30 | 11.00 |
2 | B | 50 | 10.00 |
3 | C | 20 | 15.00 |
Purchase need of 30.00 units of material. In this case delivery authorizations must be generated as below:
Supplier | Contract | Amount |
A | 1 | 9.00 |
B | 2 | 15.00 |
C | 3 | 6.00 |
However, since the contract balance 2 allows only the generation of a delivery authorization of 10.00, the remaining 5.00 must be divided among the other contracts, respecting the participation percentage of each one.
To find out the percentage of a contract during redistribution of the amount not met by a contract, calculate the percentage of each contract for this "balance". This calculation may be performed using cross multiplication, as per the example below for contract 1 of supplier A: 50% (total participation of the contracts which are to receive the "balance") is to 100%. 30% (participation of the contract that is being calculated) is to X (value to discover). Thus, X = (30 * 100) / 50 X = 60 That is, contract 1 of supplier A is to receive 60% of the balance being redistributed (5.00). Thus, 5.00 * 0.6 = 3,00. |
Supplier | Contract | Amount |
A | 1 | (9.00 + 3.00) 12.00 |
B | 2 | 10.00 |
C | 3 | 8.00 |
However, since the contract balance 1 allows only the generation of a delivery authorization of 11.00, the remaining 1.00 must be divided among the other contracts, resulting in:
Supplier | Contract | Amount |
A | 1 | 11.00 |
B | 2 | 10.00 |
C | 3 | 9.00 |
Generation of delivery authorizations by the balances of open contracts
In this method, used when there no valid supply matrix registered for the product and contract, one must calculate the total balance of all open contracts for the product. This total is 100%. From that, how much each contract represents of this total is to be calculated as percentage. This percentage is used for generating the delivery authorization for the supplier/contract.
Example:
Contract | Supplier | Balance | % of total |
1 | A | 5.00 | 12.50 |
2 | B | 20.00 | 50.00 |
3 | C | 15.00 | 37.50 |
Total | 40.00 | 100.00 |
Purchase need of 30.00 product units. Delivery authorizations must be generated as shown below:
Supplier | Contract | Amount |
A | 1 | 11.00 |
B | 2 | 10.00 |
C | 3 | 9.00 |
IF V117Documents Documents generated by MRP using date criteria
In the parameter screen for generating production orders and purchase requests/delivery authorizations, there is an assistant which defines the types of documents to be generated in the period (date) and also allows editing multiple periods at once. To do so, the Date From and Date To fields must be filled out and the desired status for the documents of this period (set or estimated) must be selected. On confirmation in the period selection list, the document type must be changed according to the selection made for the dates within the indicated period END.

Procedures
Generating a delivery authorization via Supply Matrix:
...
After processing, delivery authorizations are generated with amounts proportional to the participation percentage of each supplier included in the Supply Matrix.
