create a beas service layer object
declare this with
declare=b=ue_bsl
or
instance bsl b
with this object you can use the beas service layer as object
Example: Get information from Item
instance bsl b
b.get=Item("RM")
messagebox=<b.jstring>
Save result in JSON String
instance bsl b
instance json j
b.get=Item("RM")
j.parse=b

Result

b.get
|
instance bsl b
b.get=Item("RM")
messagebox=<b.jstring> <= return result as JSON string
messagebox=<b.ItemName> <= return ItemName from first row
messagebox=<b.code> <b.text> <= return return code and return text (status/Error text
json j
j.parse=b <= move result to a json object
|
|
b.getstring
|
The result is in property <b.value>
if result has only 1 line
{"value":{{"ItemCode":"RM","ItemName":"Raw Material / Normal"}}
if result has > 1 line
{"value":
[
{"ItemCode":"RM","ItemName":"Raw Material / Normal"},{"ItemCode":"RM_B","ItemName":"Raw Material / Batch"},{"ItemCode":"RM_B_N","ItemName":"Raw Material / Batch"},
]
}
Example:
instance bsl b
b.getstring=Item("RM")?$select=ItemCode,ItemName
messagebox=<b.value>
=> {"value": {"ItemCode":"RM","ItemName":"Raw Material / Normal"}}
|
|
b.post
|
With post command you can execute the ODATA Post
post=[command]=[json string]
Example: Create Sales Delivery document in sap
instance bsl b
b.post=SalesDelivery=&
{"CardCode":"S001","DocumentLines": [&
{"ItemCode": "RM","WhsCode":"01", "Quantity":2 }]}
messagebox=<b.code>, <b.text>, <b.value>
Return follow information
0 = all ok
79 = the created docentry number
{"DocEntry":79,"DocNum":79,"TransactionId":7000} all information as json string
|
|
b.select
|
This command is faster as b.get
But with follow limitation
- return only 1 line
- you can't parse this in json object
Example
instance bsl b
b.select=Item("RM")/ItemName/Value
messagebox=<b.value> => return item name
messagebox=<b.ItemName> => return item Name
instance bsl b
b.select=Item("RM")
messagebox=<b.value> => return empty string
messagebox=<b.ItemName> => return item Name
