Our chemicals business has a requirement that vessel determination be done in SAP. Details are as follows:
Constraints on vessel usage need to be taken into account during production. Certain vessels are always used for a certain product, although they may be used in the production of other products, if available. In a particular vessel, it is possible to produce an amount less than the total vessel capacity, but there is a lower limit on this, i.e. each vessel has a minimum production quantity associated with it. Furthermore, available vessels at production time may have a total capacity less than or greater than the required amount for production. Therefore, it may be necessary to either move the production time forward or produce an amount either less than or greater than the required amount, adjusting for the difference in the next production run for the material.
If a material needs to be produced in a particular amount (based on defined lot size / order quantity), it is necessary to optimally determine what vessels are used and quantities assigned to each vessel on the basis of vessel availability at production time and vessel capacity. Capacity is defined as the range from minimum production amount to total vessel capacity for a single vessel.
This is currently being done manually at the plant. We don't currently have a PP consultant, so any help anyone can provide is greatly appreciated. Is it possible to get at least some of this functionality using standard SAP? Perhaps something could be done using batch management? Thanks in advance.
