DBM Order Material conversion problem

[Keshi1]

Hi,

In our business for some materials we maintain conversion factors.

Ex. Material xxxx basic unit of measure is EA and EA = 208 L

We have maintained this in the material master alternative unit of measure

When we pick this item in the DBM service order to issue 5 L the confirm quantity colum would change and it will provide the calculated quantity like 4.98L and we need to put the same quantity in the quantity field otherwise it will not allow us to do the goods movement.

Pls find the attachedtment for more details.

Do you have any idea of this issue. Pls advice

Thank you in advance !!

Regards

Kesharika

Hi Kesharika,

this issue in not only a DBM issue but general because quantity
in sales unit cannot be converted to quantity in base unit
with 3 decimal points precision.
ATP check is executed in base unit.

In your case material base unit is 1 ea and sales unit is l:
208 l = 1 ea

When item for material is created with quantity 1 l
the ATP check is executed in base unit: 0.005 l (rounding up).
Based on schedule line reservation line is created: 0.005 ea - 1.040 l

Confirmed quantity is only 1 l, therefore ATP check fails and
item status is set to red.
In case of entering 1.040 l confirmed quantity is 1.040 and
ATP check is executed successfully.

We highly recommend change base unit or sales unit.
Pleae consider notes concerning alternative unit and unit conversion:

122471
523496

Solution:

To avoid the situation described above if possible, you should choose

the smallest unit of measure as a base unit of measure, if possible, so

that the alternative units of measure are a multiple of the base unit of

measure.
