Merge and update columns - r

Question

I am trying to rebuild some MS Access update query logic with R's merge function, as the update query logic is missing a few arguments.
Table link Google drive
In my database "Invoice Account allocation", there are 2 tables:
Account_Mapping Table:
Origin Origin Postal Destination Destination Invoice
country code country postal code Account
FRA 01 GBR * ZR001
FRA 02 BEL * ZR003
BEL 50 ARG * ZR002
GER 01 ITA * ZR002
POL 02 ESP * ZR001
ESP 50 NED * ZR003
* 95 FRA 38 ZR001
BEL * * * ZR002
* * * * ZR003
FRA * FRA 25 ZR004
Load_ID
ID Origin Postal Destination Destination Default
country code postal code Invoice Account
2019SN0201948 FRA 98 FRA 38 XXAC001
2019SN0201958 POL 56 GBR 15 XXAC001
2019SN0201974 BEL 50 ARG 27 XXAC001
2019SN0201986 FRA 02 GER 01 XXAC001
The default invoice account in tables (Load_ID and Status_ID) is updated by the invoice account from the Account_Mapping table.
The tables Account_Mapping and Load_ID can be joined by:
Origin country & Origin country,
Origin Postal code & Postal code,
Destination country & Destination, and
Destination postal code & Destination postal code.
In the account_mapping table, there are several "*", it means the string value can take any value. I am not able build this logic with merge function. Please help me with a better logic.
New_Assigned_Account_Final <- merge(Load_ID, Account_Mapping, by.x =
c("Origin country","Postal code","Destination", "Destination postal code"),
by.y =
c("Origin country","Origin Postal code","Destination country", "Destination
postal code"))
Desired result:
Updated Load_ID table as below.
Load_ID:
ID Origin Postal Destination Destination Default
country code postal code Invoice Account
2019SN0201948 FRA 98 FRA 38 ZR003
2019SN0201958 POL 56 GBR 15 ZR003
2019SN0201974 BEL 50 ARG 27 ZR002
2019SN0201986 FRA 02 GER 01 ZR003
For the first ID, the default ID becomes "ZR003" because, "FRA" as Origin country doesn't have a Postal code - "98", so it falls under the all "*" bucket and is allocated to ZR003.
For the third ID, the default ID becomes "ZR002" because, "BEL" as Origin country has a Postal code - "50" associated with it, and the destination postal code of "ARG" can be anything because of the "*" in the Destination postal code column, therefore it is allocated to ZR002.
Thank you for your inputs.
