Both Pricelist and Pricegrid are storing the header (speaking about the dashboard-like pricelist header) inputs, outputs and chart in a configuration field of the Pricelist/Pricegrid entity.
Mostly you will need to use the headerInputs, which contains the values entered by user to header inputs.
Values
inputs – input fields defined in Pricelist/Pricegrid logic and entered by user on the Parameters page, when defining the pricelist/pricegrid.
headerInputs – input fields defined in Pricelist/Pricegrid header logic and entered and saved by user on the header dashboard-like part of the page.
outputChartDefinition – definition of the chart, displayed in the middle part of the dashboard-like pricelist/grid header
outputs – result values of the pricelist dashboard-like header
This configuration information is stored as a Map, but in a JSON format
Example, what’s available from api.currentItem() in the pricelist header logic
Map currentItem = [
label : "PricelistHeader",
configuration :
'''
{
"inputs": [],
"headerInputs": [
{
"name": "SpecialAdjPct",
"label": "Enter Special Adjustment (in %)",
"type": "USERENTRY",
"value": 0.02
}
],
"outputs": [],
"outputChartDefinition": {}
}
''',
priceGridType : "SIMPLE",
headerTypeUniqueName: "PricelistHeaderType",
id : 363
