# FM for calculation of Weights of a BOM?

Hi ABAP,

i have/had to code a report which will display BOM´s.

According to that BOM, i need to print out the weight of the components, the weight of BOM´s in the BOM, and the weight of the BOM itself.

are there any FM´s that can calculate those values for me?

or is there any best-practice?

right now i explode the bom with CS_BOM_EXPLOSION.

parameters mehrs = 'X' if i need to calculate weights.

next step is that i calculate all the weights of the components, by either getting the weight from the BOM-position (STB-yy_ntgew), or getting it from MARA by material, or by calculation faktors.

Then when calculated all those weights, i loop over all my BOM´s in the BOM (xtlnr NE space), and calculate the weights of those by exploding them again using CS_BOM_EXPLOSION with mehrs = space.

after that looping over the exploded Bom´s and summing the previous calced values of the components.

last step is to calculate the total weight of the BOM, by adding all the values of the Bom´s in the Bom + components on Stufe = 1 which are no BOM.
