Wrong MRP element requirement qty on MD04

[josonvarghese]

Hi,

I have an issue with MD04 auto generated requirement qty.

Base unit for raw material is PAC which is equal to 500 SHT. Conversion is already set in master data. Unit of issue is maintained on SHT. A finished good material BOM consist of 2 SHT in actual. When making production order the quantity coming inside the production order is same as mentioned on BOM but on MD04 reserving 1 PAC (Correct one should be 0.004 PAC).

can anyone help me to find why its coming like this?

Kind regards

Hello Joson,

The system logic is:
The requirement in the production order is calculated in the BOM unit, for example, 94 SHT.
The requirement in MD04 is always maintained in the base unit, PAC.
According to the relationship 1 PAC = 500 SHT, 94 SHT should be 0.188 PAC. However, due to the decimal places of PAC, a round-up will happen to make sure enough material is provided for the production, so you will see 1 PAC in MD04. When you change the unit back to SHT in MD04, the conversion will based on the already round-up value 1 PAC, rather than the original value 0.188 PAC, so you will see 500 SHT instead of 94 SHT.
Actually, it is suggested that you should use the "smaller" unit as the base unit to avoid the deviation caused by the round-up.

If you want to change the decimal places of a unit, please use SSCUI 102179 - Check Units of Measurement. But as I remember, you cannot change a pre-delivered unit. So for your scenario, you may need to create your own custom unit for PAC.

Hi Matt Sui,

The explanation is good enough to understand the situation and will try changing the decimal round up. For new materials its clear that we should use the base UOM small among the conversions.

Hi Matt Sui, do you think without touching the decimal points we can solve the issue in other way? Changing UOM to smaller one is also not possible because its allocated for lot of other materials.

Actual BOM Requiremen is only 94 SHT

[josonvarghese]

If UOM is SHT

Hi Joson,

The standard UOM PAC is defined no decimal places, so the system will not show decimals .

Hello Jason, Good day!

Thank you for the reply, how does it can be changed? if we change the decimal point the quantity deducted will be same as on BOM?

Kind regards

Hello Jason,

I would like to know is there any restriction to update the decimal points for predefined UOM in S4 Hana public cloud?
