Any business will spend money on traveling, meetings, overtime &, etc. before won an Opportunity,
there is no way in Business Central to track the expenses spent on an Opportunity.

We used to add new Fields in the Journals [Payment, General & etc] to track that from the ledger entries.

Why not have an option to link the expenses to an Opportunity, please don't say create a dimension as I am recording a ton of Opportunities daily and creating dim. will create a huge list of dims.

The only way (or there is...) is to use the same concept used in the Purchase documents by linking the transaction to a Job.

Thanks
