@emre, what is Exchange Rate parameter for in Account Document Types? Does it do anything?
I notice the field in the DB is nvarchar so it wouldn’t be used for any calculations, unless maybe it tries to match the characters entered here to a Currency Template Name to get an Exchange Rate and then it does something?
I guess I am more curious to know if it will have any affect on values in the Document, or if it is arbitrary and has no real use?
That is probably a lost feature. From what I can see from source code that overrides configured exchange rate for main account but I don’t remember for what case I’ve implemented it. Probably coming from V3.
I could make use of that field in my PHP Inventory as an indicator that the Document contains a Tx Type in a Foreign Currency, so I am curious to know if I set the field to “HNL” whether or not it will have any adverse affect on the system as it pertains to internal workings of SambaPOS?
As far as I can tell, for my purpose, it does not seem to do anything?
It does if a foreign currency assigned for selected supplier account. It uses typed exchange rate instead of the exchange rate taken from currency. I don’t know what the hell I was thinking while setting it up as a nvarchar? Hmm… Surprisingly code also expects a string value and converts it to decimal. It is probably to solve a very specific issue but I really don’t remember what was it.
So if I put “HNL” in that field which cannot be converted to a number, does the code catch that and convert that to 0.00? Or to avoid possible divide-by-zero error, would it maybe convert it to 1.00?
It looks like if I have HNL in that parameter, then it ignores it entirely (no error occurs) because it cannot convert it… and that is fine for my use.
It is OK if it works fine
